CLAMP PARTICULARLY ADAPTED FOR SECURING FITTINGS TO THE FRAMES F CYCLES.

SPECIFICATION formingpart of Letters Patent No. 702,160, dated June 10,1902.

'Applicationfiled April 1, 1902. Serial No. 101,008. (No model.)

To all) whom it may concern:

Be it known that I, PER Y BENSON HARRI- soN SEABROOK, a subject of theKing of England, residing at London, England, have invented a certainnew and useful Improvement in Clamps Particularly Adapted for SecuringFittings to the Frame of a Cycle, of which the following is aspecification.

This invention relates to clamps particularly adapted for securingfittings to the frame of a cycle, and has for its object to provide adevice by which the bell, for instance, may be more readily secured toor detached from, say, the handle-bar of a bicycle than. is possible bymeans of the forms of clamp at present in use for this purpose.

According to this invention thebell'or other article is secured to thehandle-bar or other support by means of a strap, such as is commonlyemployed for this purpose, and is usually made of metal. One end of thestrap is fastened to a lug conveniently shaped to engage the support towhich the clamp is to be secured, and its freeend carries a leveradapted to operate against a fulcrum on the lug. When the strap is madeto encircle the support to which-the clamp is to be secured, the leveris placed in engagement with its fulcrum, upon which it is turned, sothat the two ends of the strap are drawn together and the clamp tightlyclasped upon the support. The fulcrum is so placed that theline oftension when the lever is in its operative position is made to passbetween it and the support, so that the tension put upon the strap 7 bythe lever serves to retain the lever inits operative position.

In the accompanying drawings, Figure 1 is a side elevation of a clampconstructed ac:

cording to one method of carrying out this invention, the clamp beingshownin position upon its support. Fig. 2 is a similar View to Fig. 1,showing the clamp unfastened. Fig. 3 is a frontview of the clamp asshown in Fig. 1. Figs. 4, 5, and 6 are similar views to Figs. 1, 2, and3, but illustrating a modified construction of clamp; and Figs. 7, 8,and 9 I are again similar views to Figs. 1, 2, and 3 of yet anothermodified construction of clamp. Like letters indicate like partsthroughout the drawings.

A U-shaped lug A, conveniently stamped upifrom sheet metal, is shaped toreceive a support B, to which it is'desiredtosecure the clamp. To oneend of the lug, which end may conveniently be closed in, is secured oneend of a metal strap 0, and to the free end of "the strap 0 is pivoted alever D. der that the leverD may be free to swing upon the end of thestrap, a slot D is provided in the lever, through which the end of thestrap is passed, the end being then turned back upon the main body ofthe strap, to which, if desired, it may be secured by riveting or othermeans, and a recess D is provided in the lower or operative end of thelever to permit the passage of the strap when fixing the clamp. The endof the lug remote from that end to which the strap is secured isconveniently left open, so that a jaw is formed adapted to receive thefree end of the strap. On each side of the lug a projection Ais'provided, placed approximately at right angles to the surface of thestrap when the latter is made to encircle the'support and serve as afulcrum for the operative end of the lever D.

Any desired device may be secured to the clamp, conveniently to thatpart of the lug which'forms the base of the U. In the drawings a bell isindicated in chain line as se- In orcured to this part of the lug; butobviously to carry the bell or any other device to be secured to thesupport.

To secure the clamp to its support, the lug is placed in position uponthe support -so that the curved part of the lug corresponds to thecurvature of the support. The strap is then carried around the support,and the operative end of the lever-that is, that end in which the slot Dis PI'OVldBd-rlS made to rest upon the projections A. The lever is thenturned upon the fulcrum, so that tension is put upon the strap 0 andsecurely binds the latter upon the support B. .Toprevent the return ofthe lever D and the consequent slacking of the strap 0, the fulcrum A isthrown out from the support by providing a shoulder A on each of theprojections A, which maintains the base of the le- ICO ver D at such adistance from the support that when brought home to the position shownin Figs. 1 and 3 the line of tension between the ends of the strap, ofwhich of course the lug A is considered a part, falls between thefulcrum of the lever D and the support, as shown in dotted lines at X X.To render the lever more secure when in its operative position, its freeend is brought over to the left of a vertical line passing through thefulcrum, so that the tension of the strap will tend to cause the leverto be carried still farther in this direction. To limit the movement ofthe lever D in this direction, the shoulder A may be continued to thetop of the lug and carried back out of the vertical line, so that itforms a stop for the lever by which the latter is maintained in thedesired position. To still further insure against the lever D beingaccidentally moved in a direction to release the clamp, a projection Emay be provided on the under side of the hell or other article securedto the lug A. The projection may be of sufficient proportions to engagethe lever as it is driven home against the lug, and the material uponwhich the projection is formed must of course be sufficiently resilientto permit the passage of the lever.

Any convenient device may be provided for adjusting the length of thestrap 0 so that the clamp may be fitted to supports of various sizes. InFigs. 4 to 6 the strapis shown as formed in two parts 0 0 respectively.The part 0 is secured by one end to the lug A, as before, and its freeend is provided with two or more orifices O placed at varying distancesfrom the extreme end. The part (3 is provided at one end with a hook 0adapted to engage any one of the orifices C in the part C, and its freeend carries a lever D similar to the lever D in Figs. 1, 2, and 3. Byengaging one or other of the orifices C of the part 0 with the hook O ofthe part C the length of the strap may be adjusted, as will be readilyunderstood. The lever D is shown in the drawings as curved instead ofstraight, as in the case of the lever D, although it may be madestraight, if desired.

The bell or other article is shown as secured to the lever, Fig. 5, andthis acts as a means by which the lever may be handled for the purposeof operating it.

Figs. 7 to 9 illustrate a modified construction of fastening-lever and amodified device for adjusting the length of the strap. Thefastening-lever D is in this case pivoted to a wire loop or link F,pivoted in turn to the lug A The strap 0 is secured at one end to thelug A as before, and its free end is provided with a hook or projection0 adapted to engage the free end of the lever D". To apply the clampconstructed according to this last method, the free end of the lever Dis brought against the under side of the projection (J on the strap 0and the link F being free to swing upon the lug A is pressed toward thesupport, so that the parts take the position shown in Fig. 7. In thispositionthe line of tension is made to lie, as before, between thefulcrumthat is, that part of the projection 0 against which the free endof the lever D bears-and the support D, this being brought about byeither curving the link F, as shown in the drawings, or, if desired, byplacing the fulcrum farther from the face of the support by anyconvenient means, such as thickening that part of the strap or providinga shoulder on the projection similar to the shoulder A on theprojections A. It will be seen in Fig. 7 that the line of tensionbetween the parts to which the ends of the link F are attached does notactually fall between the fulcrum and the support B, but passes throughthe fulcrum, as shown at Y Y. When the parts, however, are in thisposition, the tension of the strap maintains them in place, although itis preferable that the position of the parts should be such as to causethe tension of the strap to tend more directly to pull the lever towardthe support. In the construction of device shown in these figures theadjustment of the strap C is effected by means of notches A in the lug AThe notches A are placed at varying distances from the end of the lug,so that the loop F may be placed in one or other pair of notches, thuslengthening or shortening the strap.

It will be noticed that in the construction of clamp last described thelug A and strap 0 are shown as stamped up in one piece, although, ifpreferred, they may be made in two separate parts, as in the case of thetwo forms of clamps first described. Obviously the lug A and strap 0 orC may be stamped up in one piece similarly to the lug A and strap 0 WhatI claim as my invention, and desire to secure by Letters Patent, is
